Four new N-(p-chlorophenyl)carboxamides 1 - 4 of 9-phenanthrene-, 5-naphthofuran-, and 5-naphtho- and 4-naphthothiophenecarboxylic acids have been synthesized.All carboxanilides were exposed to UV oxidative irradiation in methanolic solution.In the case of 2 and 3 corresponding benzo-furophenanthridin-10(9H)-one 5 and benzo-thienophenanthridin-10(9H)-one 6 are isolated.
